Question about 1994 Dodge Caravan

1 Answer

Dodge caravan runs only on 4 cylinders and not 6

My dodge stopped running. Replaced all sensors, coil even computer. But it still is running on 4 sylinders and not 6. The timing is good. Check engine light is on. They have had it on the machine. Everything looks good. The techs are stumped.

If you have not done it already I would run a compression test.Sometimes the head gasket can blow out and leak between cylinders, if the compression shows low on the none running cylinders and they are next to each other on same side it's a good bet that's your problem.If this is it be sure when repaired the metal surfaces on block and head are checked for channeling at the blowby point.If present and not repaired it will happen again.Good luck

    addendum to previous,the computer scanner most likely won't show a compression problem but the engine light will still come on because the computer knows something is wrong but there is no way for it to check it!

2002 dodge grand caravan 3.3 v6 running rough like on 4 plugs


If one of your ignition coils on the coil pack has gone out, that would affect two cylinders, and you would only have 4 cylinders still functioning. Those two cylinders would not have spark, well, actually a jolt of high voltage current, on the wires going to the spark plugs.

Four digit codes are brand specific. Code 2302 for a Chrysler product means the secondary circuit for the coil on cylinder one is at fault. If you have replaced the coil and plug wires, it could be a problem in the wiring harness between the coil and the engine computer.

My 2007 dodge caravan is missing on the 3rd cylinder, I have replaced plugs, wires,coil pack and idel sensor and it is still not running right what could it be


i would check compression on that cylinder. you can rent the tool from some autopart stores. it just threads into the sparkplug hole and then crank the engine. check the guage and see if its within the same psi range as other cylinders.

99 dodge caravan #4 cylinder misfires, i replaced spark plug wires and spark plugs. Scanner showed #4 still misfiring, could this be the coil?


It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.
